to implement such I logic, I created a switch/case viewHelper pair, 
which allows some more flexibility too.

// traditional usage
<x:switch value="{foo.bar}">
	<x:case value="{matchValue"}>gimme</x:case>
	<x:case value="{whatever}">someting</x:case>
	<x:case default="true">fallback</x:case>
</x:switch>

// mixed usecase with condition support in cases
<x:switch return="firstMatch/allMatches">
	<x:case condition="{matchValue} = 1">gimme</x:case>
	<x:case condition="{f:count(subject:whatever)}">someting</x:case>
	<x:case default="true">fallback</x:case>
</x:switch>

switch/case might not be the best naming for the last usecase, but 
didn't find a better one back then.
